Labor's share of income has attracted interest in recent years reflecting its apparent decline. These falls, witnessed across many countries, are usually deemed undesirable. Any such assertion, however, begs the question of what is the socially optimal labor share. We address this question using...

We supplement the ‘Idea Production Function’ (IPF) with measures of R&D capital. We construct the R&D capital stock in the US, and estimate the IPF with patent applications as R&D output, allowing for a flexible treatment of R&D productivity (over 1968-2019). The estimated substitution...

Based on long US time series we document a range of empirical properties of the labor's share of GDP, including its substantial medium-run swings. We explore the extent to which these empirical regularities can be explained by a calibrated micro-founded long-run economic growth model with...

We generalize the normalized Constant Elasticity of Substitution (CES) production function by allowing the elasticity of substitution to vary isoelastically with (i) relative factor shares, (ii) marginal rates of substitution, (iii) capital-labor ratios, or (iv) capital-output ratios. Ensuing...

We compare the labour market response to region-specific shocks in Europe and the US and to national shocks in Europe and investigate changes over time. We employ a multi-level factor model to decompose regional labour market variables and then estimate the dynamic response of the employment...

This paper assesses the trends of some main macroeconomic and macro-financial variables across different time horizons related to systemic banking crises. Specifically, by gradually shifting the observation horizon of the same statistical model across time, it observes how these variables are...
